A modest reduction
8 Those costs which were reserved will follow the event. Where no order was made, costs will be in the cause. Bradken accepts that, given the complexity and number of the various issues raised in the proceedings and the competing positions taken by the parties in relation to them, this is not a case in which it is appropriate to award costs on an 'issue by issue basis'. Nevertheless, it argues that there should be discount of 25% to reflect the areas on which it succeeded and to reflect the conduct of Lynx in the course of the proceedings.
9 In this regard, Bradken succeeded in an early interlocutory application in which para 16 of Lynx's then Defence was struck out. However, this was, with respect, a relatively modest success and I do not think it should have bearing on the costs disposition.
10 In relation to a further interlocutory application, Bradken stresses the point that Lynx had insisted that it was entitled to the grant of two claim sets known at the original claims and the amended claims. Later, at trial, after the parties had prepared and filed extensive evidence in relation to both claim sets, Lynx abandoned its entitlement to the grant of the Patent with the original claims and confined its entitlement to the amended claim set. I accept that this was a reasonably substantial argument.
11 Bradken argues that it had prepared extensive evidence which became redundant by reason of Lynx's late abandonment of its entitlement to the original claims. This evidence constituted approximately 48%, it says, of Bradken's expert affidavit evidence. Bradken argues that this is a striking statistic in support of its submission for a percentage reduction in the overall award of costs in favour of Lynx. On the other hand, I note that Bradken also abandoned a substantial amount of prior art reliance at trial.
12 Another matter on which Bradken had devoted endeavours which were ultimately unnecessary was in relation to the Notice of Objection to Competency filed on 23 December 2009 by Lynx in which it put in issue complex legal arguments relating to the Court's jurisdiction, all of which required significant analysis and consideration by Bradken in its preparation for trial. Those issues were also before the Court in the second interlocutory application. They were not confined to determination or consideration at the trial. Bradken submits that the ventilation of those issues in the second interlocutory application put it to considerable expense. Bradken makes the point that the late abandonment of the Notice of Objection to Competency at trial in its entirety, and the costs thrown away by reason thereof (including Bradken's costs referable to those issues in the second interlocutory application), are matters which supports its contention that there should be a percentage reduction in costs award in favour of Lynx.
13 In addition, Bradken points to the fact that in the cross-appeals advanced by Lynx, a number of significant findings in the Delegate's decisions under appeal were put in issue. They included a challenge to the Delegate's finding in relation to deferral of the priority date of the Lynx Patent application. Lynx did not succeed at trial on that issue. I also accept that this was a reasonably substantial argument.
14 Bradken's costs incurred in relation to those dismissed cross-appeals are further matters which should be taken into account in the award of costs and provide further support for Bradken's contention that there should be a percentage reduction in Lynx's costs award.
15 Lynx, on the other hand, advances an application for indemnity costs in relation to costs thrown away by reason of Bradken's eleventh hour abandonment of certain prior art in its amended pleadings. It notes that 18 items of prior art relied on were reduced to four, with only Gilpin going to novelty. I found the remaining three, along with Gilpin, not to be proven to be part of common general knowledge. However, I do not consider indemnity costs are appropriate. In my view, the abandonment of these items was ultimately a responsible position to take in order to minimise the time and costs to be occasioned by the Court and parties at trial, although it occurred late in the day.
